Patterns of Care and Outcome in Elderly Patients With Cervical Cancer: A Retrospective Analysis

Impact of chemotherapy cycles on oncological outcomes in elders with locally advanced cervical cancer treated with concurrent chemoradiotherapy

INTRODUCTION

To investigate the association between chemotherapy (CMT) cycles and oncological outcomes in elders with locally advanced cervical cancer (LACC) who treated with concurrent chemoradiotherapy (CCRT).

METHODS

We retrospective studied 498 elders with LACC who treated with radiotherapy (RT) or CCRT between 2002 and 2018. Patients were divided into three groups: RT, CCRT with 1-4 and CCRT with 5-6 cycles of CMT. We compared progression-free survival (PFS) and overall survival (OS) among the three groups and explored survival prognostic factors via multivariate analysis and time-varying analysis effect.

RESULTS

There were 453 eligible patients; 222, 119 and 112 patients who received RT, CCRT with 1-4 and CCRT with 5-6 cycles of CMT, respectively. Patients in the RT group had older age, poorer performance status, more treatment with conventional RT technique and earlier treatment year comparing with both CCRT groups. Patients who received 5-6 cycles of CMT were less to have underweight, comorbidities and anaemia compared with the RT group. There were patients with lower FIGO stage in 5-6 cycles than in 1-4 cycles of CMT and RT groups. The 5-year PFS and OS between RT, CCRT with 1-4 and CCRT with 5-6 cycles of the CMT group were significantly different. Performance status, comorbidity, histology, FIGO stage and total received 5-6 CMT cycles were significant prognostic factors of PFS and OS. However, the benefits of receiving 5-6 CMT cycles were evidenced only within the first 2.5 years.

CONCLUSION

Elders with LACC who received 5-6 cycles of CMT concurrently with RT can improve PFS and OS, but the benefit persisted only within the first 2.5 years.

Combined radiotherapy and chemotherapy versus radiotherapy alone in elderly patients with nasopharyngeal carcinoma: A SEER population-based study

Currently, the impact of chemotherapy (CT) on survival outcomes in elderly patients with nasopharyngeal carcinoma (NPC) receiving radiation therapy (RT) remains controversial. This retrospective study aims to investigate survival outcomes in a cohort of elderly NPC patients receiving RT alone or together with CT.Clinical data on 529 NPC patients aged 65 years and older extracted from the Surveillance, Epidemiology, and End Results registry (2004-2015) was collected and retrospectively reviewed. In this cohort, 74 patients were treated with RT alone and 455 individuals received RT and CT. We used propensity score matching with a 1:3 ratio to identify correlations between patients based on 6 different variables. Kaplan-Meier analysis was used to evaluate overall (OS) and cancer-specific survival (CSS). The differences in OS and CSS between the 2 treatment groups were compared using the Log-rank test and Cox proportional hazards models.The estimated 5-year OS and CSS rates for all patients were 49.5% and 59.3%, respectively. The combination of RT and CT provided longer OS than RT alone (53.7% vs 36.9%, P = .002), while no significant difference was observed in CSS (61.8% vs 51.7%, P = .074) between the 2 groups. Moreover, multivariate analysis demonstrated that the combination of CT and RT correlated favorably with OS and CSS. Subgroup analyses showed that the combination of RT and CT correlated better with both OS and CSS in patients with stage T3 or N2 or stage III.Among NPC patients aged 65 years and older, treatment with RT and CT provided longer OS than RT alone. Furthermore, the combination of RT and CT showed a better correlation with OS and CSS in NPC patients with stage T3 or N2 or stage III.

A study of treatments and outcomes in elderly women with cervical cancer

OBJECTIVE

With the population aging, development of safe and effective treatments for elderly patients with cancer is needed. Although old age is considered a poor prognostic factor, this is not only because of the patient's disease condition or response to treatment, but also because of treatment strategy and intensity. The purpose of this study was to clarify the influence of age on treatment and prognosis in patients with cervical cancer.

METHODS

Women with stage Ib-IV cervical cancer treated at our institution between 1997 and 2014 were retrospectively analyzed. Patients were stratified by age into groups for analysis, <65 years and ≥65 years. Categorical variables were compared using chi-squared and Fisher's exact tests. Survival analyses were performed using the Kaplan-Meier method, and comparisons were made using the log-rank test. Subsequently, Cox proportional hazards models were developed to find independent prognostic factors.

RESULTS

Of 959 patients included in our study, 247 were ≥65 and 712 were <65 years of age. Elderly patients tended to be at a more advanced stage than younger patients (p < 0.001). Elderly patients more commonly had comorbidities. More received standard treatment in the younger patient group at any disease stage than in the elderly patient group (p < 0.001). Similar rates of adverse effects caused by surgery or radiotherapy were seen in patients from both groups. Although overall survival was statistically shorter in elderly patients (74.7 vs. 57.1%, p < 0.001), there was no significant difference in disease-specific survival for patients treated only with standard treatment. In multivariate analyses, clinical stage, histological type, treatment intensity, and primary surgery remained independent prognostic factors. Age was not an independent prognostic factor.

CONCLUSIONS

The influence of age on prognosis in patients with cervical cancer was less than we expected. Elderly patients might have better outcomes depending on the type of standard treatment they receive. The appropriate modality and intensity of treatment should be based on the patient's general condition and background.

Efficacy and Safety of Nimotuzumab Plus Radiotherapy With or Without Cisplatin-Based Chemotherapy in an Elderly Patient Subgroup (Aged 60 and Older) With Nasopharyngeal Carcinoma

OBJECTIVE

This study was conducted to assess the efficacy and safety of nimotuzumab combined with radiotherapy (RT) in elderly patients with nasopharyngeal carcinoma.

MATERIALS AND METHODS

The clinical data of 75 nasopharyngeal carcinoma patients, who were initially treated with nimotuzumab combined with RT, were collected and retrospectively reviewed from December 2008 to April 2014. They were aged 60 to 81 years (median 64 years). The distribution of disease was stage II in 10 (13.3%), stage III in 33 (44.0%), and stage IV in 32 (42.7%). Among these patients, 59 cases received cisplatin-based chemotherapy. Survival outcomes and treatment toxicity were analyzed using IBM SPSS 19.0 software.

RESULTS

With a median follow-up of 45 months (range, 13-78 months), the estimated 3-year local recurrence-free survival (LRFS), regional recurrence-free survival (RRFS), distant metastasis-free survival (DMFS), progression failure-free survival (PFS), and overall survival (OS) rates were 95.6%, 95.5%, 98.6%, 89.7%, and 89.2%, respectively. In the subgroup, 3-year OS rate in the patients with concurrent chemotherapy was 90.5% and 77.4% in patients without concurrent chemotherapy (Log-Rank = 1.795, P = .180). Univariate analysis showed that T stage and clinical stage were correlated with OS. Multivariate analysis indicated that age, T stage and tumor response at the end of treatment were independent prognosticators. Nine patients experienced grade 3 to 4 acute mucositis and 26 patients experienced grade 3-4 leukocytopenia, with no cases of skin rash and infusion reaction. Twelve patients developed mild liver function damage. No serious gastrointestinal or renal toxicities were observed.

CONCLUSION

The efficacy of combined nimotuzumab with RT in elderly NPC patients was encouraging and the toxicities were accepted. In addition, nimotuzumab provides a better option for elderly patients who cannot be tolerate chemotherapy.
